Assessment of water requirements of crops for the reuse of municipal wastewaters from the wastewater treatment plant at Patras, Greece
(2006)The possibilities of reuse, for irrigation, of the treated wastewaters produced in the biological wastewater treatment plant at Patras, Greece, have been examined. The practice of water reuse in soils, and cultivation, ... -
Bather density as a predominant factor for health effects related to recreational bathing: Results from the Greek bathers cohort study
(2011)Our aim was to examine the health effects on bathers from exposure to recreational seawater on three beaches with different microbiology quality and bather density through a cohort study. An initial questionnaire and a 10 ... -
Behaviour of fenitrothion residues in leaves and soil of vineyard after treatment with microencapsulate and emulsified formulations
(2007)The rate of decline of fenitrothion residues was investigated in leaves and soil of vineyard over 2 months after treatment with two different kinds of commercial formulations: emulsifiable concentrate (EC) and microencapsulate ... -
Behavioural Adaptation towards Efficient Resource Sharing under the Lack of Communication
